The impact of seasonal to inter-annual climate prediction on society, business, agriculture and almost all aspects of human life, force the scientist to give proper attention to the matter. The last few years show tremendous achievements in this field. All systems and techniques developed so far, use the Sea Surface Temperature (SST) as the main factor,(More)
In this paper we focus on the allocation of sub-carriers for the downlink OFDM-based cooperative wireless cellular networks. Based on equal power allocation, a simple sub-carrier allocation algorithm is proposed. An optimization problem is formulated to maximize the achievable system throughput with a minimum data rate guarantee for all users. The proposed(More)
Cooperative communication, a new way of communication has found its applications in almost every wireless network, from cellular to adhoc and sensor networks. The basic idea of cooperative communication is to emulate virtual antenna array to mimic a multi antenna system and hence get improved performance. In this paper, we provide performance analysis of(More)
—Efforts have been made on voice enabled navigation, but to use the voice enabled systems more effectively, we need to exploit the marvels of web semantics properly, especially with the aspect of blind. Voice enabled applications have already been introduced by several companies but " Voice Enabled Browsing " is an area yet to be discovered. In this study(More)
Multi-carrier cooperative relay-based wireless communication is of particular interest in future wireless networks. In this paper we present resource allocation algorithm in which sub-carrier pairing is of particular interest along with fairness constraint in multiuser networks. An optimization of sub-carrier pair selection is formulated through capacity(More)
—E-Marketing is the most immediate, flexible and cost effective marketing tool available in business today. Businesses have to embrace the web as a platform; as a way to do business in this day and age. This study is focused on the marketing of organic textile products through e-marketing and how the internet and web based marketing tools can help to create(More)
In this paper we address the resource allocation problem in cooperative relay network. We provide a comparative analysis of two basic protocols namely Amplify and Forward (AF) and Decode and Forward (DF), by implementing different sub-carrier allocation techniques with optimized power allocation. Our analysis is focused on total achievable system throughput(More)
Relay-based cooperative wireless networks are considered one of the cost-effective solutions to meet the demands in future wireless networks. In this paper, we address the resource allocation problem in multi-user Two-way relaying wireless networks. In order to maximize the cell sum-rate with sub-carrier pairing while ensuring load balancing at relays, we(More)
